French scientist announces first T lymphocyte " attack " route chart

French scientist films next T lymphocyte atttack the route chart of tumor cell successfully recently, announced cell of this kind of immunity " fight " whole process. This achievement will conduce to the remedial level that raises cancer. 　　 According to French country science the research center announces 15 days, this research reachs French country science by health of nation of French Courier institute, France and medical institute expert of research center immunity and microscope expert collaboration are finished. Experts use double photon microscope to film issued T lymphocyte to identify the cell that cause disease, whole process that surround and atttacks the cell that cause disease. According to saying, this still is belonged to on the world first. 　　 T lymphocyte is a kind of big cell with the mainest function inside airframe immunity system group, this kind of cell has the capacity that identifies the antigen of the cell that cause disease such as tumor cell, when discovering this kind of antigen, t lymphocyte can launch attack to the cell that cause disease, with special enzymatic kill the cell that cause disease. Before French scientist, although scientific group knows T lymphocyte the effect that produces in immune system, but fail to observe from cellular level all the time the working process of the T lymphocyte that is activationed. 　　 French scientist discovers in consider and observing, in the tumour of dispel antigen, no matter tumor is in what growth phase, rate of T lymphocyte motion is very rapid, it is about minutely 10 micron; Contrary, should have T lymphocyte infuse the tumor cell of antigen 3 after coming 4 days, the athletic speed of T lymphocyte is apparent slow down, and often jib, average the rapiddest rate does not exceed minutely 4 micron, below the action of T lymphocyte tumor stops development. After tumor is thoroughly atrophic, t lymphocyte restores to move with very rapid rate again. 　　 Researcher is summed up from this say, existence sends ill antigen and T lymphocyte is T lymphocyte development to the identifying of this kind of antigen the cell that cause disease and the premise that kill the cell that cause disease. In addition, of speed of T lymphocyte motion accelerate or be to make clear not " enemy " the cell causes ill cell namely, or it is occurrence issue of airframe immunity system, "Called lost battle " . 　　 It is reported, french scientist had undertaken in the research of this one domain old. Current, they are reaching treatment of palace neck cancer to have clinical research to the action of T lymphocyte. (Reporter Lu Suyan)
